Sorry to hear that, Hawk. I've finished first city without any issues and I'm also on win7. Can't see how a game could mess up a system that bad. It doesn't install any device drivers or other stuff that could have access to kernel or core OS stuff, perhaps it was sth else, just the timing makes you believe it's MDK. In any case, I hope you got it resolved
